I would definitely prefer a policy-based approach.

And I think the interfaces for the "other type" would be fairly simple
-- even built-in to the xints. Passing an xint to a nothrow_xint can
be implicit, no different from a normal copy of a nothrow_xint, and
even allows a noexcept move. nothrow_xint -> xint would work well as
an explicit conversion that throws on special values.

Actually, that latter conversion, if implicit, would essentially give
the same result as the current library without the need for the
explicit "Will throw if given NaN" on every single function.
